Alex Weimer –
I recently purchased PA144-432-19-3-2CBP dual band antenna.
It was received very well packed ! Assembly was very easy and straight forward.
The antenna was made of quality products !
After assembly the SWR was flat across the full fequency spectrum on both bands.
I am very pleased with your product and would recommend them to anyone.
The additional gain over my old antenna made a great difference !
Thank You
